ÓThe subject of the invention is a coded modulation method and a transmitter and receiver for implementing the method. During the method according to the invention, the information bits are allocated based on their error sensitivity, the information bits are divided into parallel signal streams, channel coding is performed on each data stream with at least two different code rates per degree with a channel encoder (4, 5), where the different code rates are applied according to the error sensitivity of the information bits, the information bits channel coded with different code rates are sorted at different times and the channel coded and signal space points are assigned to the enumeration information bits to create modulation symbols. The transmitter suitable for carrying out the method according to the invention is equipped with a first multiplexer (3), a channel encoder (4, 5) for step-by-step channel coding, a step-by-step sorting unit (51, 52, 53, 54, 61, 62, 63, 64) and a device for assigning channel coding information bits to signal space points. The receiver suitable for implementing the method according to the invention has a device suitable for evaluating signal transmission (13), demodulating modulation symbols, channel decoding and sorting.
